Thanks for your reply.

I ultimately would like to create a product/service to serve a market; although, I can't say I don't have an itch to get into code.

One reason as to why I posted this is because I wanted to hear from hackers whether a physician with nothing more than domain-knowledge would be able enough to provide significant contribution to a growing startup. I've lurked about for some time and have noticed a stigma against non-hackers looking to start up.

But your post is reassuring and encouraging.
